This question already has answers here: what is the Endpoint for sending multiple message at once without using topic in FCM(firebase cloud messaging) V1 (1 answer) FCM batch messages URL (1 answer) Closed 2 days ago. API : https://fcm.googleapis.com/v1/%7B+parent%7D/messages:send Request body { “message”: { “registration_ids”: [ “DEVICE_TOKEN_1”, “DEVICE_TOKEN_2” ], “notification”: { “title”: “postman test 2”, […]

Because Firebase Console has the functionality to send notifications to Android/iOS devices without subscribing to topics or targeting specific tokens, and it can also send notifications to users who have logged in within a certain number of days, I would like to ask if it’s possible to achieve the same thing through the API.

I don’t have experience using Firebase, and I’m trying to test send a silent push notification through FCM to an Android app I’m developing. It seems I can only send regular notifications from the Firebase admin (which I’ve been able to do), but not the silent ones I’m trying to test.

I can’t figure out how to use the A/B testing feature in FCM to split my audience in half and test two different send times for a push notification. Do they need to be separate tests? Any steps you can provide on how to achieve this would be very helpful!

please tell me who has encountered this problem. I’m currently working with firebase notifications, I want to make sure that messages from the same sender are merged, like in WhatsApp. They all come to me separately

I recently disabled the legacy Cloud Messaging API and switched to the new Firebase Cloud Messaging API (V1) as shown in the screenshot below:

I’m trying to send push notifications using the Firebase Admin SDK, but I’m not receiving any notifications.
The error “Requested entity was not found” occurs.
